CVE-2014-4667

Status Candidate

Overview

The sctp_association_free function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not properly manage a certain backlog value, which allows remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet.

Red Hat Security Advisory 2014-1167-01

Red Hat Security Advisory 2014-1167-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's futex subsystem handled reference counting when requeuing futexes during futex_wait(). A local, unprivileged user could use this flaw to zero out the reference counter of an inode or an mm struct that backs up the memory area of the futex, which could lead to a use-after-free flaw, resulting in a system crash or, potentially, privilege escalation. A NULL pointer dereference flaw was found in the way the Linux kernel's networking implementation handled logging while processing certain invalid packets coming in via a VxLAN interface. A remote attacker could use this flaw to crash the system by sending a specially crafted packet to such an interface.

Ubuntu Security Notice 2337-1 - A flaw was discovered in the Linux kernel virtual machine's (kvm) validation of interrupt requests (irq). A guest OS user could exploit this flaw to cause a denial of service (host OS crash). Andy Lutomirski discovered a flaw in the authorization of netlink socket operations when a socket is passed to a process of more privilege. A local user could exploit this flaw to bypass access restrictions by having a privileged executable do something it was not intended to do. Various other issues were also addressed.

Ubuntu Security Notice 2335-1 - An flaw was discovered in the Linux kernel's audit subsystem when auditing certain syscalls. A local attacker could exploit this flaw to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS). An information leak was discovered in the rd_mcp backend of the iSCSI target subsystem in the Linux kernel. A local user could exploit this flaw to obtain sensitive information from ramdisk_mcp memory by leveraging access to a SCSI initiator. Various other issues were also addressed.

Ubuntu Security Notice 2333-1 - A bug was discovered in the handling of pathname components when used with an autofs direct mount. A local user could exploit this flaw to cause a denial of service (system crash) via an open system call. Toralf reported an error in the Linux kernels syscall auditing on 32 bit x86 platforms. A local user could exploit this flaw to cause a denial of service (OOPS and system crash). An information leak was discovered in the control implementation of the Advanced Linux Sound Architecture (ALSA) subsystem in the Linux kernel. A local user could exploit this flaw to obtain sensitive information from kernel memory. Various other issues were also addressed.

Red Hat Security Advisory 2014-1023-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. It was found that Linux kernel's ptrace subsystem did not properly sanitize the address-space-control bits when the program-status word was being set. On IBM S/390 systems, a local, unprivileged user could use this flaw to set address-space-control bits to the kernel space, and thus gain read and write access to kernel memory. It was found that the permission checks performed by the Linux kernel when a netlink message was received were not sufficient. A local, unprivileged user could potentially bypass these restrictions by passing a netlink socket as stdout or stderr to a more privileged process and altering the output of this process.

Red Hat Security Advisory 2014-0913-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's futex subsystem handled the requeuing of certain Priority Inheritance futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system. It was found that the Linux kernel's ptrace subsystem allowed a traced process' instruction pointer to be set to a non-canonical memory address without forcing the non-sysret code path when returning to user space. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system.
